The present invention relates to an electrostatic discharge body used for mounting a termination box of an optical communication cable and removing a trouble caused by electrostatic discharge charged on a human body, and various antistatic devices equipped with the same.
[0002]
[Prior art]
In recent years, communication using an optical communication cable has become a core of many communication networks such as an intranet, the Internet, a cable television, and a mobile phone network due to a high-speed and large-volume data transmission power. In particular, with the explosive growth of computer networks and the rapid spread of wireless communication means such as mobile phones, the demand has been increasing year by year, and optical communication cables have been laid everywhere.
[0003]
For example, in a clean room, a server room, or the like, it is common to interconnect a client computer and a server computer or precision equipment via a hub to form a network. Also in this case, a wiring system for connecting a client and a server using an optical communication cable with low noise as a transmission path is increasing. A terminating box described later is provided at an end of the optical communication cable, and the terminating box and the distribution board are usually independently installed on an upper wall surface in a room. Further, the hub to which the optical communication cable is connected is arranged as close to the termination box as possible, taking into account the arrangement of the computer and the indoor environment.
[0004]
[Problems to be solved by the invention]
However, in the conventional method of arranging the termination box and distribution board on the upper part of the wall in a clean room or server room, when performing work such as extension branching of optical communication cables or maintenance, the operator needs to stepladder each time. Since it must be used at a high place, the workability such as extension branching and maintenance of the optical communication cable is poor. In particular, since optical communication cables are vulnerable to bending, it is necessary to lay the optical communication cables so as not to bend suddenly in the wiring work. Under such constraints, the wiring work of the optical communication cable has become more difficult, and there has been a problem that the work efficiency of the conventional installation method is generally not good. Further, in the conventional configuration, since the termination box, the hub (hub box), and the distribution board are individually installed, there is a problem that a large mounting space is required.
Also, in a clean room handling semiconductor devices or a server room in an environment where precision equipment is operated, if workers are charged, the electrostatic discharge may damage the device, ignite flammable substances, fire, dust on products, etc. There has been a problem that inconveniences such as mixing and malfunction of electronic devices occur.
[0005]
The present invention has been made in view of the above problems, and an object of the present invention is to provide an electronic device that can easily perform wiring and maintenance of an optical communication cable and the like, save space, and cause electrostatic discharge. It is an object of the present invention to provide an electrostatic discharge body which can be widely used for measures for preventing malfunctions and the like, and an electrostatic discharge device equipped with the same.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, a static electricity countermeasure device according to a first aspect of the present invention includes a surge current induction circuit having a ground side terminal and an induction side terminal, a distribution box, and a termination box of an optical communication cable containing a hub. An electrostatic discharge body formed of a conductive material is grounded to the ground terminal.
[0007]
According to a second aspect of the present invention, there is provided the antistatic device according to the first aspect, wherein the electrostatic discharge body is a tabletop made of a conductive material.
[0008]
According to a third aspect of the present invention, there is provided the antistatic device according to the first aspect, wherein the electrostatic discharge body is a mouse pad made of a conductive material.
[0009]
According to a fourth aspect of the present invention, there is provided the antistatic device according to the first aspect, wherein the electrostatic discharge body is a brush made of conductive short fibers.
[0010]
According to a fifth aspect of the present invention, there is provided the antistatic device according to the first aspect, wherein the electrostatic discharge body is a carpet made of a conductive material laid on free access.
[0011]
According to a sixth aspect of the present invention, there is provided the antistatic device according to any one of the first to fifth aspects, wherein the electrostatic discharge body is connected to the ground terminal via a sensory means for detecting discharge.
[0012]
The optical communication cable is mainly laid in a clean room, an operating room, a server room, a building management room, and the like for manufacturing semiconductors and chemicals, but can be applied to high-rise apartment buildings, schools, government offices, and the like. Inside the room, a computer or its peripheral devices are arranged, and these are connected by a cable via a hub. A desk (including a table) is provided in the room, and a storage case is attached to a side of the desk. The storage case is divided into at least two sections, one of which is a termination box, and the other stores precision equipment such as a hub (hereinafter, referred to as a hub box). An outlet for commercial power will be provided inside the termination box.
[0013]
In the above configuration, the termination box and the hub box are arranged on the side of the wall surface or the desk, so that the operator can open the storage case while staying on the floor without using a stepladder or the like, and directly connect the optical communication cable. And hub wiring work and maintenance work can be easily performed. Further, since the termination box and the hub box are integrally integrated in the storage case, the size and size of the box can be reduced. In the case where the cable for the commercial power supply is provided in the termination box, a separate outlet is not required, so that the space can be saved correspondingly.
[0014]
Further, a power circuit is laid along with the optical communication cable, a power circuit for connecting peripheral devices such as a hub (HUB) is provided, and power is supplied to the power circuit via the power circuit, and a power circuit is connected in parallel with the power circuit. Connect to the induction terminal of the surge current induction circuit. Incidentally, the surge current induction circuit shown here reacts at a high speed to a high voltage surge current to flow a surge current to the ground side. Thus, when a surge current is generated, the surge current does not flow to the peripheral device connected to the power supply circuit, but escapes to the ground side.
[0015]
